[strongSwan] Traffic selectors routing issue for IPv6 TS with 128 prefix

Hi Sachin,

Since the determining factor for the source IP is the local traffic
selector, i.e. fc01:eab:xx::xx/128 (which I suppose is
fc01:eab:xx:z::92/128 in both cases), and the availability of a matching
IP address, the source IP should be the same.

Try increasing the log level for the KNL subsystem to 2 (see [1]) and
compare the output during the two scenarios.

Tobias
